  1. 1. On control of cascaded H-bridge converters for STATCOM applications

    University dissertation from Chalmers University of Technology

    Author : Ehsan Behrouzian; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; STATCOM; cascaded H-bridge converters; Modular Multilevel Converters MMC ; FACTS.;

    Abstract : Cascaded H-bridge (CHB) converters are today considered the industrial standard for STATCOM applications, mainly due to their small footprint, high achievable voltage levels, modularity and reduced losses. However, there are still areas of research that need to be investigated in order to improve the performance and the operational range of this converter topology for grid-applications. READ MORE

  2. 2. Operation and control of cascaded H-bridge converter for STATCOM application

    University dissertation from Chalmers University of Technology

    Author : Ehsan Behrouzian; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular Multilevel Converters MMC ; cascaded H-bridge converters; STATCOM; FACTS.;

    Abstract : In the last decade, particular attention has been paid to the use of Modular Multilevel Converters (MMC) for grid applications. In particular, for STATCOM applications the phase leg of the converter is constituted by a number of single-phase full-bridge converters connected in cascade (here named Cascaded H-Bridge, CHB, converter).

  3. 3. Cascaded Converters with Gate-Commutated Thyristors Experimental Verification and Auxiliary Power Supply

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Tomas Modeer; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis describes an effort to investigate the use of gate-commutated thyristors(GCTs) in cascaded converters. Cascaded converters, such as modularmultilevel converters (M2Cs) and cascaded H-bridge converters (CHBs), haveproved to be especially suitable in high-voltage, high-power applications. READ MORE

  4. 4. Grid Connection of Permanent Magnet Generator Based Renewable Energy Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Senad Apelfröjd; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VAWT; H-rotor; Tap Transformer; Cascaded H-bridge Multi-Level; Renewable Energy; Wind power; Wave power; Marine Current Power; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Renewable energy is harnessed from continuously replenishing natural processes. Some commonly known are sunlight, water, wind, tides, geothermal heat and various forms of biomass. The focus on renewable energy has over the past few decades intensified greatly. READ MORE
